flange oil seal with a lithium-base extreme pressure
lubricant.

3. Use J-21057, as shown in figure 61, to press seal
into carrier bore until gauge plate is flush with the
carrier shoulder and seal flange. Turn gauge plate
180° from installed position; seal must be square in
carrier bore to seal properly against pinion flange.
